I’m pleased to announce that django-firebird with django 1.6 support is underway.

Django 1.6 is still in alpha state, so django-firebird 1.6 too.
Then, you can see the current status at the master branch . The master branch has the “in develop” version. If you need stable support (django 1.5) take a look at stable/1.5.x

What are the changes in database field?
The main changes is on transaction management and including BinaryField
